RS8561XK

Jiangsu RUNIC Tech · Precision Op Amps · SOIC-8

RS8561XK from Jiangsu RUNIC Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection; the datasheet states this pin can be left floating.
2 -IN input Negative (inverting) input of the single amplifier; the datasheet's absolute maximum signal input range is (V-) - 0.5 V to (V+) + 0.5 V.
3 +IN input Positive (noninverting) input of the single amplifier; common-mode range is (V-) - 0.1 V to (V+) + 0.1 V.
4 V- power_in Negative (lowest) power supply; single supply operation is 2.9 V to 5.5 V referenced to V-.
5 NC unconnected No internal connection; the datasheet states this pin can be left floating.
6 OUT output Amplifier output, swinging rail-to-rail; absolute maximum output current is ±55 mA.
7 V+ power_in Positive (highest) power supply; the supply difference V+ - V- is 2.9 V to 5.5 V (absolute maximum 7.0 V).
8 NC unconnected No internal connection; the datasheet states this pin can be left floating.
